How Fleet Fuel Budget Calculator Works
This tool works by grouping vehicles by type, pricing each group from unit count, annual miles, and fuel economy, and adding the group costs into one fleet budget.
- Step 1
Group the fleet
Sort vehicles into groups with similar miles and fuel economy, such as vans, pickups, and sedans.
- Step 2
Enter units and miles
Type the vehicle count and the average annual miles per vehicle for each group.
- Step 3
Enter MPG and contract price
Use group MPG from fuel card data and the fleet fuel price, gasoline or diesel.
- Step 4
Read the fleet budget
The calculator shows fuel volume and cost per group, the fleet total, and cost per vehicle.
Fleet Fuel Budget Calculator Formula
The formula sums group fuel costs, where each group cost equals units × miles ÷ MPG × price.
Group Gallons = Units × Annual Miles per Unit ÷ Group MPG
Fleet Budget = Σ (Group Gallons × Fuel Price)
Cost per Vehicle = Fleet Budget ÷ Total Units
- Units
- = number of vehicles in the group
- Group MPG
- = average fuel economy of that vehicle group
- Fuel Price
- = contract or average price per gallon
Worked Example
- 8 cargo vans × 25,000 mi ÷ 18 MPG = 11,111 gal × $3.60 = $40,000.00.
- 4 pickups × 20,000 mi ÷ 20 MPG = 4,000 gal × $3.60 = $14,400.00.
- 3 sedans × 15,000 mi ÷ 32 MPG = 1,406 gal × $3.60 = $5,062.50.
- Fleet budget = 16,517 gal (62,525 L) and $59,462.50, or $3,964.17 per vehicle across 15 vehicles.
Fleet Fuel Budget Calculator Conversion Table
The table scales fleet size at 20,000 miles (32,187 km) per vehicle, 20 MPG, and $3.60 per gallon, with the saving from a 1 MPG improvement.
| Vehicles | Gallons / Year | Liters / Year | Annual Budget | Monthly Budget | Saving at 21 MPG |
|---|---|---|---|---|---|
| 5 | 5,000 | 18,927 | $18,000 | $1,500 | $857 |
| 10 | 10,000 | 37,854 | $36,000 | $3,000 | $1,714 |
| 25 | 25,000 | 94,635 | $90,000 | $7,500 | $4,286 |
| 50 | 50,000 | 189,271 | $180,000 | $15,000 | $8,571 |
| 100 | 100,000 | 378,541 | $360,000 | $30,000 | $17,143 |
| 250 | 250,000 | 946,353 | $900,000 | $75,000 | $42,857 |
A 1 MPG gain across a 20 MPG fleet cuts fuel spending by 4.8%.
What is a Fleet Fuel Budget Calculator?
A Fleet Fuel Budget Calculator is a commercial planning tool that aggregates fuel expenses across every vehicle in a company fleet.
Fuel is 20% to 40% of operating cost for most light commercial fleets. A fleet budget built vehicle by vehicle is slow, and a single fleet-wide average hides costly vehicle groups. The Fleet Fuel Budget Calculator works at the group level, which matches how fleet managers buy, assign, and replace vehicles.
The results support annual budgets, fuel card limits, and vehicle replacement plans. The 1 MPG saving column shows the value of driver training and tire programs.
What are the uses of a Fleet Fuel Budget Calculator?
There are 5 main uses of the Fleet Fuel Budget Calculator, including annual budgeting, fuel card limits, and replacement planning.
